The urine and plasma levels of iodine can be measured by Quest and LabCorp. Curiously, almost everyone comes back low. If, so, where are the high people who are contributing to the range? Do levels of thryoid hormone affect these levels? Is iodine bound in the blood? By proteins, fats or other more specialized molecules?
